Solve for a in terms of b

 

\(3a+4b=a-8b+24\)

 

You are asked to rearrange this so that you have 'a' out the front by itself.  The other side can have not a's in it.

 

Follow these steps, one at a time, to get your answer.

 

1) take   1a    away from  BOTH sides

2) take 4b away from BOTH sides

3)Divide BOTH sides by the number in front of the a   (which should be 2)

 

4) there might be a little tidying to do on the right side but the left side just has 'a' now.  That is what you want   

 

Come back with your working and the answer  cool

AND

 

I need to see how you attempt my teaching questions that I have asked you.

 

It is no wonder you cannot learn if you do not even attempt to follow your teacher's (my) instructions.
